I hope so too. This is the top thing my DD wants to do this trip. When it looked like we'd be waiting multiple hours for the meet & greet in Norway, I'd spoken to one of DD's babysitters who will be down at WDW at the same time as us. I'd asked her if I could pay her to join us in Epcot one day and I would wait in line while she took DD to do things. Now that we can hopefully score fastpasses for this, we can still meet up with the babysitter and her family (babysitter's mom is a good friend of mine), but have fun together rather than me being stuck in an hours long line.
Do they still have the characters greet during the parade? I thought they usually shut down the meet & greets of the characters that are in the parade for the length of the parade to maintain the illusion that there's only one of each character.
And I'd recommend you repost your question a few days after 4/20 if someone hasn't already started a thread for people to post their Anna and Elsa wait times.
